Radiometric dating vs carbon dating

How does the geologic timescale fit with the view of a young earth? There have been different methods of measuring carbon-14 since Willard Libby pioneered the radiocarbon dating technique in the 1940s – from the radiometric techniques of gas proportional counting and liquid scintillation counting to the more recent accelerator mass spectrometry (AMS).AMS has become the standard in the industry for measuring carbon-14 content and offers several advantages over radiometric techniques.In contrast, it measures the carbon-14 directly, relative to the carbon-12 and carbon-13 present, rather than measuring the products of its radioactive decay.Gas proportional counting involves converting samples to CO gas followed by detection and counting of the beta particles.Liquid scintillation counting involves converting the sample into a carbon-rich liquid, which is then added to a scintillator.By measuring the amount of uranium and ‘radiogenic lead’ in these crystals, one can calculate that, if the decay rate has been constant, about 1.5 billion years must have passed.(This is consistent with the geologic ‘age’ assigned to the granites in which these zircons are found.) There is a significant amount of helium from that ‘1.5 billion years of decay’ still inside the zircons.

What is Progressive Creationism and is it biblical?

Beta Analytic no longer offers radiometric dating by liquid scintillation counting.

All samples submitted for radiocarbon dating are measured by AMS. You only need to include the confirmation code in the packag​e​​.

The point is that radiometric dating is not the sure thing that it has been made out to be over the last century.

When beta particles are emitted, the scintillator will emit a flash of light.
